Transcript
ECE 222 Lab 5 – Phasors In this lab, you will build two RLC circuits and observe the magnitude and phase relationships between the various components. 1. Design two different circuits, each with an AC voltage source and at least one resistor, one inductor and one capacitor. You can make these as simple or as complicated as you want. Simple is recommended! It is fine to use the same circuit as in Lab 2 for one of them, but you don’t have to. 2. For each circuit, calculate the phasor voltage (magnitude and angle) across each component. Assume the source has a phase angle of 0o. Note: this is at a single fixed frequency of your choice. You can either use the same frequency for both circuits, or different ones. 3. Simulate your circuits in LTSpice and verify your calculations. 4. Build and test your circuits. The voltage magnitudes are easily displayed and measured on the scope. For the phase angles, display the source and component voltage simultaneously and determine the phase angle of the component voltage with respect to the source. Your report should include your circuit designs, phasor calculations, LTSpice schematics and simulation results, screen shots of test results and discussion.
